Network Traffic Analysis and Security Monitoring with Wireshark

Understanding what happens on your network at the packet level is essential for any cybersecurity or IT professional. This course guides you through the process of capturing, filtering, and interpreting network data to uncover hidden threats and optimize infrastructure performance. You will develop the ability to transform raw data into actionable security intelligence. By studying packet structures and traffic flows, you will learn to spot unauthorized access attempts, malware communication, and configuration errors that compromise network integrity. What you'll learn: - Capture and analyze live network traffic using standard sniffing techniques - Apply advanced display filters to isolate specific protocols and suspicious activities - Interpret core network protocols including TCP/IP, HTTP/S, and DNS - Perform Deep Packet Inspection (DPI) to identify security vulnerabilities and anomalies - Understand the impact of modern encryption protocols like TLS 1.3 on traffic visibility - Analyze traffic patterns relevant to cloud-integrated and remote work environments Starting with core networking terminology and the Wireshark interface, the material progresses into detailed protocol analysis and practical security investigation techniques. The course is designed for beginners in networking or cybersecurity and requires no prior experience with traffic analysis tools.
